Intermetatarsal Bursitis: The Forefoot Condition Often Confused with Morton’s Neuroma

Medically reviewed by Dr. Tom Biernacki, DPM — Board-Certified Podiatric Surgeon — Balance Foot & Ankle, Howell & Bloomfield Hills, MI. Last updated April 2026.

Intermetatarsal bursitis — inflammation of the small bursa located between the metatarsal heads in each intermetatarsal web space — produces plantar forefoot pain nearly identical in distribution and quality to Morton’s neuroma, yet requires different treatment. Distinguishing bursitis from neuroma is clinically important because cortisone injection is appropriate first-line treatment for bursitis but should be used with caution in neuroma (risk of perineural fibrosis), and alcohol sclerosing injection is specific to neuroma.

Distinguishing Features

Location and character: both intermetatarsal bursitis and Morton’s neuroma produce pain at the web space between the metatarsal heads — most commonly the third (between third and fourth metatarsal heads). The pain of bursitis tends to be a broader, more diffuse aching, while neuronal pain is often more electric or burning with radiation into the toes. Mulder’s click: a positive Mulder’s click (palpable ‘click’ produced by laterally compressing the metatarsals while pressing on the web space from below) is more specific for neuroma than bursitis — though it can be positive in either condition with significant bursitis. Ultrasound: the critical diagnostic tool — bursitis appears as an anechoic (dark) fluid-filled sac between the metatarsal heads, while a Morton’s neuroma appears as a hypoechoic (darker than surrounding tissue) solid ovoid mass. The two conditions frequently coexist — a neuroma creates local inflammation that secondarily causes bursitis, and both can be seen on ultrasound simultaneously. Response to treatment: bursitis responds rapidly and completely to a single ultrasound-guided corticosteroid injection; neuroma is slower to respond and may require multiple treatment sessions.

Treatment

Isolated bursitis: ultrasound-guided corticosteroid injection (triamcinolone 20–40mg into the bursa) produces complete resolution in 70–80% of cases. Metatarsal pad/orthotic: off-loading the metatarsal heads with a metatarsal pad distributes pressure away from the inflamed bursa. Footwear modification: wider toe box and lower heel to reduce metatarsal head loading. Neuroma with secondary bursitis: treat both — the neuroma-specific treatment (alcohol sclerosing injection series, NSAID course) combined with bursal injection. Dr. Biernacki at Balance Foot & Ankle performs diagnostic ultrasound to differentiate intermetatarsal bursitis from Morton’s neuroma and provides targeted ultrasound-guided treatment.

Frequently Asked Questions

What does Morton’s neuroma feel like?

Morton’s neuroma typically causes a burning, stinging, or electric-shock sensation in the ball of the foot, often radiating to the 3rd and 4th toes. Many patients describe the sensation of stepping on a pebble or having a bunched-up sock underfoot.

Can Morton’s neuroma go away on its own?

Very early-stage neuromas may improve with footwear changes alone. However, established neuromas typically require treatment — padding, orthotics, cortisone injections, or alcohol sclerosing injections. About 20–30% eventually need surgical excision.

What is the success rate of Morton’s neuroma surgery?

Neuroma excision has a 75–85% success rate for long-term pain relief. The risk of permanent numbness in the affected toes should be discussed before surgery. Minimally invasive approaches have similar outcomes with faster recovery.

Differential Diagnosis: What Else Could It Be?

Several conditions share symptoms with Morton’s Neuroma and are commonly misdiagnosed in the first office visit. Considering these alternatives is part of every Balance Foot & Ankle exam:

• Capsulitis (2nd MTP). Pain at 2nd-toe base rather than between toes; drawer test positive.
• Stress fracture. Single-point tenderness over a metatarsal shaft, not between toes.
• Freiberg’s infraction. AVN of metatarsal head, classic radiograph flattening.

If your symptoms don’t fit the textbook pattern, ask your podiatrist which differentials they ruled out — that conversation often shortcuts months of trial-and-error treatment.

Most Common Mistake We See

The most common mistake we see is: Adding a cushioned insole instead of a metatarsal pad. Fix: place the metatarsal pad PROXIMAL to (behind) the metatarsal heads — not directly under them.

Warning Signs That Need Same-Day Care

Frequently Asked Questions

Which is better for plantar fasciitis?

The shoe with more cushioning and a stronger rocker typically wins for plantar fasciitis. See full comparison for our specific verdict.

Which lasts longer?

Both options typically last 300-500 miles for runners or 9-12 months for daily walkers. Material durability varies; check our detailed comparison.

Which is better for flat feet?

Flat feet need stability or motion control. The neutral option is not ideal unless paired with a custom orthotic.

What is Metatarsalgia?

Metatarsalgia is a common foot/ankle condition that affects mobility and quality of life. Understanding the underlying cause is the first step in successful treatment. Our podiatrists at Balance Foot & Ankle perform a hands-on biomechanical exam, review your activity history, and use diagnostic imaging when appropriate to identify the root cause—not just treat the symptom. Many patients have been told to “rest and ice” without a deeper diagnostic workup; our approach is different.

Symptoms and warning signs

Common signs of metatarsalgia include pain that worsens with activity, morning stiffness, swelling, tenderness when palpated, and difficulty bearing weight. If you experience sudden severe pain, inability to walk, visible deformity, numbness or color change, contact our office the same day or visit urgent care—these can signal a more serious injury such as a fracture, tendon rupture, or vascular compromise. Diabetics with any foot wound should seek same-day care.

Conservative treatment options

Most cases of metatarsalgia respond to non-surgical care: structured rest, supportive footwear changes, custom orthotics, targeted stretching and strengthening protocols, anti-inflammatory medications when medically appropriate, and in-office procedures such as ultrasound-guided injections. We also offer advanced therapies including MLS laser therapy, EPAT/shockwave, regenerative injections, and image-guided procedures. Treatment is sequenced from least invasive to most invasive, and we explain the rationale at every step.

When is surgery considered?

Surgery is reserved for cases that fail 3-6 months of well-structured conservative care, when there is structural pathology (severe deformity, complete tear, advanced arthritis), or when imaging shows damage that will not heal without intervention. Our surgeons have performed 3,000+ foot and ankle procedures and prioritize minimally-invasive techniques whenever appropriate. We discuss recovery timelines, return-to-activity milestones, and realistic outcome expectations before any procedure is scheduled.

Recovery timeline and prevention

Recovery from metatarsalgia varies based on severity and chosen treatment path. Conservative cases often improve within 4-8 weeks with consistent adherence to the protocol. Post-procedural recovery may range from a few days (in-office procedures) to several months (reconstructive surgery). Long-term prevention involves footwear assessment, activity modification, structured strengthening, and regular check-ins with your podiatrist if you have a history of recurrence. We provide written home-exercise plans and digital follow-up support.
